How cyber secure is dwsim

[KnarfSkidbacke]

Cybersecurity is coming getting more important iin all areas, thus I wonder:
1.Is all data (models, calculations) handeled localy in my computer or are there hiddne features connecting to the cloud ?

2.Can (model) data be encrypted and/or compressed with password protection - the decryption/decompress is handled on the fly when the model is used, thus after use the model is encrypted/zipped and can not be changed unless the password is known.

3.Is there a feature to track who did change what in the model file ? (If a team works on a model one can se who changed what)
